Field Summary

static int	ANY_TYPE This code does not represent a specific type.
static int	ANY_UNORDERED_NODE_TYPE The result is a node set and will be accessed as a single node, which may be null if the node set is empty.
static int	BOOLEAN_TYPE The result is a boolean.
static int	FIRST_ORDERED_NODE_TYPE The result is a node set and will be accessed as a single node, which may be null if the node set is empty.
static int	NUMBER_TYPE The result is a number.
static int	ORDERED_NODE_ITERATOR_TYPE The result is a node set that will be accessed iteratively, which will produce document-ordered nodes.
static int	ORDERED_NODE_SNAPSHOT_TYPE The result is a node set that will be accessed as a snapshot list of nodes that will be in original document order.
static int	STRING_TYPE The result is a string.
static int	UNORDERED_NODE_ITERATOR_TYPE The result is a node set that will be accessed iteratively, which may not produce nodes in a particular order.
static int	UNORDERED_NODE_SNAPSHOT_TYPE The result is a node set that will be accessed as a snapshot list of nodes that may not be in a particular order.

Field Detail

ANY_TYPE

public static final int ANY_TYPE

This code does not represent a specific type. An evaluation of an XPath expression will never produce this type. If this type is requested, then the evaluation returns whatever type naturally results from evaluation of the expression.

See Also:

Constant Field Values

NUMBER_TYPE

public static final int NUMBER_TYPE

The result is a number.

See Also:

Constant Field Values

STRING_TYPE

public static final int STRING_TYPE

The result is a string.

See Also:

Constant Field Values

BOOLEAN_TYPE

public static final int BOOLEAN_TYPE

The result is a boolean.

See Also:

Constant Field Values

UNORDERED_NODE_ITERATOR_TYPE

public static final int UNORDERED_NODE_ITERATOR_TYPE

The result is a node set that will be accessed iteratively, which may not produce nodes in a particular order. This is the default type returned if the result is a node set and ANY_TYPE is requested.

See Also:

Constant Field Values

ORDERED_NODE_ITERATOR_TYPE

public static final int ORDERED_NODE_ITERATOR_TYPE

The result is a node set that will be accessed iteratively, which will produce document-ordered nodes.

See Also:

Constant Field Values

UNORDERED_NODE_SNAPSHOT_TYPE

public static final int UNORDERED_NODE_SNAPSHOT_TYPE

The result is a node set that will be accessed as a snapshot list of nodes that may not be in a particular order.

See Also:

Constant Field Values

ORDERED_NODE_SNAPSHOT_TYPE

public static final int ORDERED_NODE_SNAPSHOT_TYPE

The result is a node set that will be accessed as a snapshot list of nodes that will be in original document order.

See Also:

Constant Field Values

ANY_UNORDERED_NODE_TYPE

public static final int ANY_UNORDERED_NODE_TYPE

The result is a node set and will be accessed as a single node, which may be null if the node set is empty. If there is more than one node in the actual result, the single node returned might not be the first in document order.

See Also:

Constant Field Values

FIRST_ORDERED_NODE_TYPE

public static final int FIRST_ORDERED_NODE_TYPE

The result is a node set and will be accessed as a single node, which may be null if the node set is empty. If there are more than one node in the actual result, the single node returned will be the first in document order.

Constructor Detail

XPathResult

public XPathResult()

Method Detail

getResultType

public int getResultType()

The code representing the type of this result, as defined by the type constants.

Returns:

the code representing the type of this result

getSnapshotLength

public int getSnapshotLength()

The number of nodes in the result snapshot.

Returns:

the number of nodes in the result snapshot

getSingleNodeValue

public Node getSingleNodeValue()

The value of this single node result, which may be null.

Returns:

the value of this single node result, which may be null

iterateNext

public Node iterateNext()

Iterates and returns the next node from the node set or null if there are no more nodes.

Returns:

the next node

public boolean getBooleanValue()

Returns the value of this boolean result.

Returns:

the value of this boolean result

getStringValue

public String getStringValue()

Returns the value of this string result.

Returns:

the value of this string result
